Existing nuclear energy relies on a process called fission, where a heavy chemical element is split to produce lighter ones.

Nuclear fusion works by combining two light elements to make a heavier one.

Fusion is the process that powers the Sun, along with active “main sequence” stars, and other high magnitude stars.

Nuclear fusion is a reaction in which two or more atomic nuclei of hydrogen are brought in close enough proximity to form one or more different atomic nuclei and subatomic particles (neutrons and/or protons).

The difference in mass between the products and the reactants is manifested by the release of a very large amount of energy.

This mass difference results from the difference in atomic binding energy between the atomic nuclei before and after the reaction.

It is fundamental to the energy release.

Ultimately, this energy could be used to heat water and drive steam turbines to generate electricity.
